Specification of Letters Patent. Patented Apr. 26, 1910- Application filed September 13, 1907. Serial No. 392,799.

To all whomit may concern:

Be it known that I, Ilnmux F. IV. IIUEG, residing at Long Island Cit v, in the county of Queens and State of New York, have inand Improved Roll-Making Machine. of which the following is a specification.

My present invention, which relates generally toimprovements in means for moldingdough into the desired shapes preparatoryto baking, more particularly has for its purpose, toprovide a roll making machine for baker of a simple and economical-conthe manipulation of the plastic material is suclrthat it is positively reduced to the desired shape uniformly and (prickly, and in which tlwsevcral parts have special relation whereby thevean be readily adjusted for producing rolls of different forms and sizes. V l -That the essentials of my present invention may be. readily umlerstood by' those skilled in the art to which itappertains, it should be here stated, that in its complete make up it includes ameans known as the which curls or winds the matea spiral or coiled condition which is afterward formed into the desired roll shape, ready to be discharged onto an off take or conveycr ready for the oven.

Heretofore in machines of the character mentioned, the curling devices or means, usually cooperate with the shaping drum, to effect the spiral winding or coiling of the preformed plastic sheet. v

From practical experience with machines in which the drum forms a coiiperative part of the curling means, I have found that the. operation of curling does not meet the desired requirements, since the coils or rolls are more or less irregularly formed.

My invention in its generic nature differentiates from the general type of machines noted, in providing, in connection with dough sheet or hat forming devices and the drum, :1 coiling means independent. of the drum, thattakes up the plastic or dough sheet and curls it into uniformly shaped coils and then delivers said coils (o be engaged and rolled by the drum.

My invention also comprehends an improved eonsti'u -tion of coilii'ig means, that takes the sheet and coils it, before it is delivered onto the drum to be rolled, in which is included a means for checking a slipping action of the fdouglras it is being coiled, whereby to provide for positively coiling the dough sheet so soon as it is engaged by the coiling devices and continuing the rotary action of the coiled plastic body until it is discharged and taken up by the final reducin or rolling means.

Another object of my invention is to provide a simple, improved and cooperative arrangement of parts whereby the dough masses are reduced to a hat or sheet, then coiled, reduced or rolled to shape, and then delivered onto an off take ready for the oven.

In its subordinate features my invention consists in certain details of construction and peculiar combination of-parts pointed out in the appended claims, and illustrated in the accompanying drawings in which Figure 1, is a perspective view ofmy invention. Fig. 2, is a vertical longitudinal section thereof on the line 9-2 on Fig. 3. Fig. 3, isa transverse section thereof, taken substantially on the Fig/ t, is a diagrannnatic view showing different shapes of drum rims.

In carrying out my invention, I arrange the several parts of the machine as erally shown on Fig. 1, by reference to which it will be observed the frame work comprises two opposite side members, each consisting of a base portion 1 and an upright portion 1, and which are relatively rigidly held by the cross shafts presently referred to, and stay rods Journaled in bearings 10l0 formed on the upper ends of the frame members 1, 1 is the drive shaft 3, provided with their usual fast or loose belt pulleys 4-4 as shown. Mounted in the long bearings on the front end of the side fran'les is the shaping or rolling drum 6, the shaft of which carries a large gear 6 that meshes with a smaller gear 7 on the drive shaft 3 from which it is driven, it also meshing with and driving a gear 80 on the shaft that carries a pulley S which forms a part of the roll off take devices, hereinafter referred to. The drum (3 consists of a spider frame having a circumferential shaping rim 30, that is shaped in cross section to suit the, Shape and length of the rolls to be made, it, in the drawing, being shown coneaved as at (-1 and with straight ends (31 whereby, in connection with the convexcd compression plate 9 presently again referred to, a roll of line 3-3 on Fig.

gen-

r the drum,

a substantially-egg shape is made as shown in Fig. 3, it being understood, however, that 1 I of the side frame, and which carries a gear (1, that drlven to rotate in the direction the cross sectional shape of the drum rim and the compression plate may be readily varied to suit the desired wanted. Suitably mounted on the top of shape of the roll i roller a, fixedly mounted on across shaft 6, ournaled 1n bearing 0 on the back edges indicated by the arrow 0, by a gear f,

l i a mounted on the main drive shaft as shown.

the frame work and in the vertical axis of 3 is a bottomless hopper 10, into which the batches of the'do'ugh are placed, the sides 10 of said hopper being in vertical alinement with the side flanges of the drum, and the lower ends 10, 10 of the said side project down beneath the drum ilanges, (see Fig. 3,) the lower edge of the forward end 10 being slotted as at b to straddle the reducing roller 12, mounted on the drum shaft 3, in rear of the hopper, and positioned to cooperate with the drum to reduce the material into a sheet or bat'and feed the said sheet forward to the curling devices presently described.

V13 designates a scraper adjust-ably secured to the hopper to clear the drum face, and 14 designates a scraper blade that engages the reducing roll, it being mounted on a rock shaft 15, having an angle arm 15, provided with an adjusting screw 15", for regulating the pressure of the scraper on the reducing roller 12.

The compression plate 9 before referred to, is of width to extend within the drum flanges and said plate is of stout spring metal and extends over the discharging portion of the drum, it being secured at the upper end only by connection with the fiattened portions 17 of a tie bolt 17. To hold the compression plate S) under a desired tension with respect to the drum, with which it cooperates to form the final roll reducing means, secured to the plate 9 with which engages an adjusting screw 18, by which proper adjustments of the compression plate 9 is pro vided for. The outer or delivery end of the compression plate, extends forward of the axis of the drum and tcrminatesover the endless conveyer or off take belt 19, that takes around the drum pulley S- and around another pulley 81, mounted at any suitable point in the bake shop, it being understood the parts are'drivcn to carry the shaped rolls in the direction indicated by the arrow on Fig. 2. The upper end of the compression plate 9 is disposed approximately in the horizontal axial plane of the drum (3, and it is inclined outwardly from the drum whereby to form a mouth to receive the coiled dough portions :1; as the discharge from the curling means, the construction of which and the manner inwhich they are mounted relatively to the dough reducing and shaping devices, forming the essential features of my present invention.

The curling means, the construction of which is best shown in Fig. 2, comprise a a spring metal arm 17" is pendently tions, they enter he roller a, is positioned near the upper portion of the down going side of the drum 6 and it projects into the hollow rim of the said drum, whereby to engage. the dough sheet as it is carried down with the drum, and to insure a positive coiling or turning up of the end of roller a has a seriesof transverse teeth or serrations gthat grip the dough sufliciently to hold it from slipping back. The roller a cooperates with a guard plate ii, that extends from the receiving end ofthe c'urling means concentrically with the roller a to the discharging end of the said curling means, its lower end being made fast to'the the tooth'edor serrated surface of the roller a, the guard h .is formed witlra' series ,of small apertures or indentations h, the said series preferably corresponding with the serrations or teeth on the roller'a, tures or apertures preventing slipping actionof the dough as it is carried forward through the coding passage and insuring with the teeth on the roller a,a positive rolling or coiling action of the dough, continuously, as it passes through the coiling passage.

The ends of the coiling passage are closed so that in dischar ing the coiled dough porfietween the flanges of the drum, and to provide for ositively starting the coiling as soon as the ough comes from the roller 12, the perforated guard plate is fastened at its lower end only in order to get the desired spring or tension 'at the receiving end for engaging the curled ends of the dough as will be clearly understood by reference to Fig. 2.

Operation: The dough batch'o'r mass, of which the roll is to be made, is dropped into the hopper onto the drum (3, which in con nection with the reducing roll spreads the mass into a sheetor bat,s which as itis Carried forward engages which traveling'in the opposite direction of drum 6, arrest-s the advance of the dough sheet and causes its end to curl as indicated on Fig. 2, which action continues on the still advancing portions of the sheet until the entire shected mass has heencurled into a coil bctweenthe roller a and theguard h, when such indenthe said dough sheet, the

the toothed roller a, I

by reason of the stationary guard IL, and the toothed rotating roller (1- the coil is carried forward through the passage between the plate I and the roller a, continuously coiling or rotating as it; passes to the discharge end of the said passage, when the coil in its expanded shape drops back into the combined shaping and final reducing passage formed by the drum and the opposing compression plate 9, where it is again constantly turned over and over and at the same time compressed to final shape, and caused to pass out from the roller and compressing plate onto the off take or conveyer, as clearly indicated in Fig. It is understood, that as soon as one sheet mass has been curled up and enters the coiling passage, another batch of dough is placed into the hopper to be operated on, and so on. By hanging, as it were. the compression plate from one end, providing it with a spring tension device, capable of adjustment as shown, the desired pressure of the compression plate can be easily provided for to suit the diameter of the material being worked, by providing curling means that operate independent. of the drum and which include a positively adjusted or sized curling passage, a uniform and positive curling of all the batches, is obtained, and the irregular coiling. which I have found occurs when the curling means comprise a serrated member that cooperates with the drum, is absolutely overcome. By serrating the curling roller (1 and its (.0- operating plate It, a sufficient grip is exerted by the teeth on the roller (1 and resistance by the indentures or apertures in plate It to insure a constant turning over of the coil as itpasses forward with the roller 1.! to the fina': :ha ping means.

\Vhile for simplicity of structure and compact arrangement of parts, I prefer to position the curling means with respect to I the drum and the reducing roll, its arrangement, as also the detail arrangement of the other parts, may readily be modified without departing from my invention as defined in the appended claims.

It will be understood that the peripheral face or rim of the drum may he of varied shapes, for example as shown by Fig. 4: to provide for the desired shapes of rolls.

Having thus described my invention, what, I claim and desire to secure by Letters Patent is 1- The combination with the drum, the means for primarily reducing the plastic material to a sheet and a means independent of the other means for coiling the plastic sheet; of a compressing ilate that extends concentrically under the discharging end of the drum, and means for holding the said plate under spring tension, as set forth.

The combination with the drum and the curling devices as shown, of the compression plate freely sustained at its upper end to a cross bar of the main frame, said plate being turned to extend over the down going sideof the drum, a spring member pendent from the plate and an adjusting screw for engaging said member as set forth HERMAN F. \V.
